The mutagenic 2(5H)-furanones resulting from the chlorination of lignohumic substances in water disinfection and paper pulp bleaching are known to be inactivated by thiols. The objectives of the present study were to characterize the kinetics of an inactivating reaction, isolate

Environmental and molecular mutagenesis, 25(4), 284-287 (1995-01-01)
The mutagenicity of chlorinated humic drinking waters is accounted for mainly by a single contaminant, 3-chloro-4-(dichloromethyl)-5-hydroxy-2(5H)-furanone (MX), as assessed in Salmonella typhimurium strain TA100. In the present study 3,4-dichloro-5-hydroxy-2(5H)-furanone (mucochloric acid, MA), another drinking water contaminant much less potent as

The genotoxic effects of three chlorohydroxyfuranones (CHFs), 3-chloro-4-(dichloromethyl)-5-hydroxy-2[5H]-furanone (MX), 3-chloro-4-(chloromethyl)-5-hydroxy-2[5H]furanone (CMCF) and 3,4,-dichloro-5-hydroxy-2[5H]furanone (MCA), which are formed as byproducts of water disinfection with chlorine, were investigated in bacterial differential DNA repair assays in vitro and in animal-mediated assays in vivo.

One group of disinfection byproducts of increasing interest are the halogenated furanones, which are formed in the chlorination of drinking water. Among these halofuranones is mucochloric acid (MCA, 3,4-dichloro-5-hydroxyfuran-2(5H)-one), and mucobromic acid (MBA, 3,4-dibromo-5-hydroxyfuran-2(5H)-one). Both mucohalic acids (MXA) are direct
Mucochloric acid action on phi X174 DNA: a comparison to other chlorine-substituted 2(5H)-furanones.
R T LaLonde et al.
Chemical research in toxicology, 10(2), 205-210 (1997-02-01)
The action of the drinking water mutagen 3,4-dichloro-5-hydroxy-2(5H)-furanone (MCA) on the plasmid phi X174 converted this initially closed circular, supercoiled (SC) DNA to its relaxed (R) and linear (L) forms. Kinetic analysis of this process gave results coinciding with a
